"When did we start speaking and why?" This is the question all scientists try to solve and they have some answers. Our brains didn't only change size but also they became more complex so how could we speak and other animals couldn't? Because animals according to the article "Can breath and swallow at the same time so the range of possible sound is limited". It is difficult for scientists and paleoanthropologists to find if they were able to speak or not because "Spoken words don't leave fossils" according to the article but they believe it started at about one million years ago. The reason we are not sure yet is because scientists and archaeologists find older and older fossils that are evidence for the use of language.
